If I remember correctly from the interview the word moles were used. So my guess is that some of nonracial traits will start to be shared between each race and gender.
Like maybe the muscle slider Hyur and Roe have. Obviously moles will be a trait so I'm thinking scars will also get the treatment. Meaning Lalafell can finally have battle scars.
That said I'm wondering if we will get more face selection options such as elderly for example. Though for me personally I really hope they expand on the color selections for hair, lipstick and makeup along with things like the moles and scars etc.
